To all "whom it may concern.

Be it known that I, LOUIS CAUL, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of ()hio, have invented acertain new and useful Improvement in Carbonating-Machines, of which the following isa full, clear, and exact description, reference being had to the accompanying drawings.

My invention relates to machines for carbonating water and, more particularly, relates to the class of carbonating machines in which the gas and water are mixed and then delivered to the spigot or faucet which is controlled by the person drawing the carbonated water.

The object of the invention isto provide a simple compact machine which will perform its functions with certainty, be housed within a comparatively small amount of space, and further, to provide a machine in which the handle of the faucet or spigot will, by means of intermediate connections, cause the operation of the motor which pumps the water to the mixing chamber, the pressure of which water forces the mixed and water from the mixing chamber to the spigot.

Generally speaking, the invention comprises the elements and combinations thereof set forth in the accompanying claims.

Reference should be had to the accompanying drawings forming a part of this specification, in which Figure 1 shows the carbonating machine and cooling device for the carbonated water, in elevation, the casing which surrounds the machine being shown in section; Fig. 2 is a front elevation of the carbonating machine; Fig. 3 is a top plan view of the base, the pumps and connecting pipes, with the motor and mixing chamber removed: Fig. 4 is a side elevation of the spigot with the end cap and a portion of the operating handle re moved, showing the electrical switch; Fig. 5 is a central vertical section through the head of the spigot and the associated parts;

Fig. 6 is a section taken upon the line 66 of F 1g. 5; Fig. 7 is a face view of the valve .member which cooperates with the head of the spigot, and Fig. 8 is a central section of a'portion of the spigot operating handle and a portion of the .yoke.

. In Fig. 1 is represented an arrangement of carbonating machine, cooling device for thecarbonated water, spigot for delivering the carbonated water and a casing which incloses the carbonating machine and cooler, and at the same time forms a counter below upon which the Vessel to receive the carbonated water may be placed.

Upon the base 1 (see Fig. 3) is mounted two pumps 2 which are exactly similar in their construction. At one end these pumps communicate with pipes 3,.which are joined to a single pipe l, which pipe is in communication with a source of water. At the opposite ends, the pumps communicate with pipes 5, which are connected to the union 6 which is in turn connected to a vertical pipe 7. Upon the base 1 are mounted two pairs of uprights 8 which are joined at their upper ends by yokes 9. Bearing journal boxes are sup orted upon the opposite yokes and a sha t 10 is supported within the journal boxes. At the opposite ends of the shaft 10 are crank arms 11 which carry crank pins 12. Associated with the crank pins are links 13 which are pivoted upon a yoke member 14 carried by the pump piston 15, which operates within the cylinder of the pump. The crank arms 1-1 are arranged at an angle of 180 degrees with respect to each other upon the shaft 10, so that the pumps 2 work alternately in supplying water to the mixing chamber.

Upon the base 1 is mounted a motor 16 which, in the present instance, is an electrical motor of standard type. The motor carries upon its shaft :1 gear 17 which meshes with a gear 18, which is secured upon theshaft 10.

Upon one of the uprights 8, the bracket 19 is supported, which bracket is provided with an extending arm 20 upon which the mixing chamber 21 is mounted. The mixing chamber is somewhat cylindrical in shape at the lower portion and more or less elliptical in shape at the upper portion. The casing is formed in two parts, respectively secured together. the casing is formed with an outlet link 22 which has a nut or boss 23 upon the lower part thereof. This nut or boss 23 rests upon the upper part of the extending arm 20 of the bracket. Below the bracket a pipe 24 extends, which is joined to the lower part The lower part ofv of the mixing receptacle by means of a the arm 20 of the bracket.

The pipe 7 which, as will be remembered,

isthe pipe that conducts the water that has passed through the pumps, is connected to the upper part of the mixing receptacle by means of a suitable connection and delivers the pumped water to the interior of the mixing reee tacle. Within the receptacle is journale a shaft 26, indicated in dotted lines in Fig. 2. Upon the shaft is mounted a suitable agitating device 27. The shaft 26 extends beyond the walls of the receptacle, and to its outer end is secured a gear 28, which is in mesh withthe gear 18, previously mentioned. a

From the above description it will be obvious that as the motor is set in motion, it will actuate the gear 17, which through the gear 18 will rotate the shaft 10 and throu h the connection of the gears 18 and 28 wi rotate the agitators within the mixin@ receptacle.

ituated conveniently to the base is a gas tank 29, which tank is adapted to hold carbon di-oxid under pressure. This tank is connected with the mixing receptacle by means of the pipe 30 so that gas under pressure is supplied to the interior of the mixing upon the operation of the handle 36. The spigot 34 is formed with ahead 37, which "the spigot connects with the pipe 33 has recessed portions on both sides, in one of which portions is fitted a valve member 38. 'This valve member is held in position by means of a cap 39 which is fitted to close the recessed end in the head and interposed between said valve member and the surface with which it coiiperates is a washer of suitable packin material. The valve member 38 is secure upon a stub shaft 40, which in turn is connected upon one arm of a yoke 41. For convenience in assembling the spigot, the yoke 41 is made in two parts secured together at their inner ends by a screw 41, as shown in Fig. 8. A stud 36 is firmly clamped between the parts of the yoke for the purpose of supporting the operating handle-36. Exteudingothrough the central portion of dy is a-passa way 42 which U ring carbonated water. This passage 42 connects with a side assageway 43 which is formed in the he of t e s igot, and forms the center of thecircle within which the valve member 38 rotates. A curved assage 44 in the valve member 38 exten s from the center thereof to near'its outer edge. Consequently the passageways 43 and 44-are in constant communication, regardless of the rotary movement which may he imparted to-the valve member through the operation of the handle 36. The outer'end of the passage is formed with an opening 45 which is adapted to communicate with other openings in the spigot head.

- By reference to Fig. 7 the construction of the passage 44 and the opening 45 will be understood, and in Fig. 6 is shown the various ports with which the port 45 is adapted to communicate. The port 46, shown in Fig. 6, communicates with a passage 47, shown in dotted lines in Fig. 5, while the port 48 communicates with a passage 49, also shown in Fig. 5, so that as the handle 36 is turned and by this means the valve member 38 is also turned, the port 45 may be made to coincide with either of the ports 46 or 48 and supply carbonated water to either of the passages 47 or 49.

The passage 47 communicates with the recessed portion 50 which is fdrmed in the lower part of the spigot head and will flow out through 'the nozzle 35 giving a thick heavy stream of carbonated water, while the passage 49 communicates with an extended mouth-piece 51, which mouth-piece extends substantially to the lower portion of the part 35. Through the central part of the extension 51 is a small opening 52 which,

' as is well known in the art, will supply a thin forceful stream of carbonated water.

The port 45 is brought into register with the orts 46 and 48 by movement of the hand e forward or toward the operator. However, the handle 36 may be operated to the rear of the vertical position or away from the-operator when the port 45 will be brought into communication with a port 53, which by means of a suitable passage, similar in all respects to the passagev 47, will permit the carbonated water to flow through the recessed portion 50 and through the nipple 35. The pur ose of this construction will be later ex lalned.

Upon the si e of the spigot head, opposite to that already described, is a recess similar to the one previously described. Thisrecess is likewise closed by means of a cap 54 through which extends a stub shaft 55 to which is secured one of the members of the yoke 41, joined to the handle 36. Within the ca and upon the shaft 55 is secured a coile spring 57 which, as shown in Fi 4, has at the end thereof a head-piece 58. his head-piece is formed with a projectin finger 59 and the end of the head is slighty bent so as to form a projecting curved portion.

In the head of the recess is secured a disk 60, which is of insulating material. Upon this disk is secured an electrode 61 which, as

'36 is drawn in the direction of the arrow A,

the shaft 55 will be turned in a counterclock-wise direction which will cause the spring 57 to be flexed and when the tension becomes suflicient the finger 59 will be dislodged from its engagement with the stop 63 and the head 58 will be projected into engagement with the parts 62 upon. the electrode 61. The projecting portion 62 is provided with a slight, transverse depression, and the end of the head 58 is turned downward to engage said depression when the two parts are in connection. Therefore, when the stub shaft 55 is rotated in a direction to break the connection between the spring 57 and the electrode 61, the depression 62 will prevent the withdrawal of the down-turned portion of 58 until the spring has been placed under sufficient tension to not only disengage the parts, but to swing the projection 59 beyond the stop 63. Therefore, the disengagement will be instantaneous and the distance of separation between the parts great enough to prevent arcing.

The electrode 62 is connected by means of a suitable insulated connection with one of the binding posts upon the motor. Another electrical conductor is connected with the other binding post for the motor and is electrically connected with the spring 57 secured to the stub shaft 55 but insulated therefrom in any suitable manner. In this conductor is interposed a battery X, indicated in Fig. 4. The conductors pass through holes bored in the spigot, as indicated 1n dotted lines in Fig. 4.

It will be apparent from the foregoing description that when the handle 36 is pulled forwardly in the direction of arrow A, the members 58 and 62 will engage which will complete the electrical circuit through the battery X and supply an electric current to the motor, which in turn will pump water through the mixing receptacle where it will be impregnated, with gas, and further, will force the carbonated water through the'cooling coils 31, pipe 33' and through the passageway 42 in the spigot. If the handle 36 be drawn forwardlysuch a distance that the port 45 is in connection with the port 46 then the carbonated water will pass through the passageway 47 and will be delivered through the nipple 35 in a thick slow stream.

Should the handle 36 be pulled forward far enough so that the port 45 registers with the port 48, then the carbonated water will be delivered through the passageway 49, through the member 51 and issue from the nipple in a thin stream with great. velocity. i

It may happen that when it is desired to draw carbonated water from the carbonating machine that the pressure within the mixing receptacle is already as great as the machine is designed to stand, so that if the spigot were merely opened, the carbonated water would issue with suflicient force without the employment. of the pump. To accommodate-such a contingency, the arrangement heretofore described of bringing into register the port 45 and the port 53 by the movement of the handle 36 in the direction indicated by arrow B, has been provided. As before described, when the parts are brought into such relation, the carbonated water may issue through the nozzle and as the handle is being moved in the direction opposite to that necessary to make electrical connection, the projection 59 on the head 58 of the switch-spring will leave the stop 63 and swing idly to the rear. For the purpose of ascertaining the pressure of the carbonated water within the coil 31 and the mixing recepjacle 21, a pressure gage 64 is provided and is mounted upon the body of the spigot 34 in convenient position for the user of the device to observe the recorded pressure.

From this description it will be seen that, if desired, water may be drawn from the spigot without the operation of the pumps; or water maybe pumped into the system to a certain pressure, indicating on the pressure gage, without drawing it from the spigot by turning the operating handle in the direction of the arrow A a distance sufficient to operate the switch, but not suflicient to bring it to register the ports 45 and 46. Or water may be drawn at the same time it is being pumped by simply advancing the handle farther in the same direction until the port- 45 is brought into communication with either of the ports 46 or 47, and the members 58 and 62 of the switch will remain in contact while the spring 57 yields to accommodate the excess movement of the stub shaft 55.

It will be apparent that various changes may be made in the arrangement of parts of the carbonating machine, as shown, withoutdeparting from the spirit of the invention, and I do not limit myself further than that which is specifically recited in the claims.
